I wouldn't try to mix EFI and BIOS in a dual boot system. Did it, with Mint, and without being able to recall the detail, it was a mess, and I recovered by reinstalling Windows and then installing Mint in EFI mode. Fortunately the Windows registration code had been stored someplace mysterious and invisible, so the reinstallation just picked it up fine, and then Mint went in just fine after ooting from the DVD in EFI mode and then doing the install after that, and everything was fine. I have a vague recollection of having to create the EFI partitions again manually. Or maybe that was some other misadventure with EFI. The other experience I have in this matter is, never, never update the BIOS. I did, having foolishly listened to advice that it was necessary, which it was not, and the main board was hosed, and the only way to recover was finding a shop somewhere in the Himalayas north of Watford who extracted the chip and reinstalled it. There is a lot to be said for old main boards that just do BIOS! Al On Fri, 22 Feb 2019 12:00:02 +0000 main-request@lists.alug.org.uk wrote:
